Strontium hafnate (SrHfO) is a perovskite-structured ceramic compound combining strontium and hafnium oxides, belonging to the family of high-refractory and dielectric ceramics. This material is primarily investigated in research contexts for high-temperature applications and as a thermal barrier coating material, particularly in aerospace and gas turbine environments where hafnium-based ceramics offer superior oxidation resistance and thermal stability compared to conventional alternatives like yttria-stabilized zirconia. Its potential extends to electronic applications in capacitors and as a gate dielectric in advanced semiconductor devices due to its high permittivity and thermochemical stability.
